Process for substituted cyclohexenes and its products

Abstract

The present invention relates to a process for 3r-N-Monomethylamino-4 cis-phenyl-4 trans-ethoxycarbonyl-cyclohexene and its N-substitution products which are generally useful as analgesics.

Having described our invention, we claim: 
     
       1. A compound of the formula: ##STR4## wherein R is selected from the group consisting of ##STR5## 
     
     
       2. The compound of claim 1 wherein R is ##STR6## 
     
     
       3. The compound of claim 1 wherein R is ##STR7## 
     
     
       4. A compound as set forth in claim 2 wherein R is capryloyl. 
     
     
       5. A compound as set forth in claim 2 wherein R is 4' chlorobenzoyl. 
     
     
       6. A compound as set forth in claim 2 wherein R is carboxyethylcarbonyl. 
     
     
       7. A compound as set foth in claim 2 wherein R 2'-aminobenzoyl. 
     
     
       8. A compound as set forth in claim 3 wherein R is carbamyl. 
     
     
       9. A compound as set forth in claim 3 wherein R is ethyl carbamyl. 
     
     
       10. A compound as set forth in claim 3 wherein R is butyl carbamyl. 
     
     
       11. A compound as set forth in claim 3 wherein R is 2'carboxyphenyl-carbamyl.
